TECHNICAL FIELD
[0001] The utility model belongs to the technical field of building construction, and particularly relates to a turnover single-layer super-high industrial plant wall connecting piece embedded part. BACKGROUND
[0002] Now many industrial plants are high in single-layer height due to use function requirements, and are mostly 4.5-9 m high. When a disc buckle frame is used for engineering scaffolding, the general step distance is 2 m, the longitudinal distance is 1.5 m, the transverse distance is 0.9 m, and the wall connecting piece is 3 steps and 2 spans or 2 steps and 3 spans. During construction, due to the high floor height, the outer frame needs to be erected to 6 m or more above the current floor (i.e. 3 steps or more) before the upper structure is poured. According to the provisions of 7.5.1 of the Safety Technical Standard for Building Construction Socket Type Disc Buckling Steel Pipe Scaffolding JGJ / T 231-2021: the working frame vertical rod should be accurately positioned and should be erected according to the construction progress, and the one-time erection height of the double-row outer working frame should not exceed two steps of the uppermost wall connecting piece, and the free height should not be greater than 4 m. Therefore, when the upper structure is constructed, the outer frame needs to be temporarily connected, and after the upper wall connecting piece is formed, it can be removed. After the structure is formed, the wall connecting piece can be increased in the form of holding column according to the needs. The commonly used temporary connection measure is a throw support, as shown in Figure 5 and Figure 6 .
[0003] When the Figure 5 form is used, the following problems exist:
[0004] 1. Since the throw support is connected by the extended transverse wall connecting piece, no reinforcement measures are taken at the end, and in actual implementation on site, it is found that the end shakes greatly and is not safe enough;
[0005] 2. A large area of transverse wall connecting piece steel pipes is increased, which increases the steel pipe rental cost;
[0006] 3. The post-stage removal and reconstruction investment is large, which affects the subsequent construction to some extent;
[0007] When the Figure 6 pre-embedded steel pipe is used, the following problems exist:
[0008] 1. The floor thickness is only 13 cm, and if a steel pipe is embedded in the floor, the steel pipe is not firmly embedded due to insufficient embedding depth;
[0009] 2. If a steel pipe penetrates the floor, there is a large difficulty in removal, and the post-stage hoisting and sealing is not convenient, and the sealing engineering quantity is large.
[0010] In summary, a new type of embedded part needs to be designed to provide help for high wall connecting pieces. UTILITY MODEL CONTENTS
[0011] In order to solve the above problems, the utility model discloses a kind of turnover single-layer super-high industrial plant wall connecting piece embedded part, simple structure, stable and reliable, and most components can be recycled, save cost.
